Description

  The present invention relates to a takoyaki device that can be heated while being vibrated to bake and cook a substantially spherical takoyaki.

  As a typical prior art, for example, Patent Document 1 can be cited. In this prior art, the motor provided on the bottom lid via an elastic body is vibrated in the vertical and horizontal directions by rotating the vibration generating weight, and this vibration is transmitted to the frame supported by the housing by a spring. While the heating plate mounted on the frame is vibrated in the vertical direction and the horizontal direction by this vibration, the heating plate is heated by an electric heater which is a heating means, so that takoyaki can be cooked.

  In addition, as another prior art in Patent Document 1, a follower fixed to a motor output shaft is inserted into a cam hole, and vibration generated by rotation of the motor output shaft is transmitted to the frame through the shaft. The heating plate is heated by the electric heater as a heating means while the heating plate mounted on the frame is vibrated in the vertical direction and the horizontal direction by the transmitted vibration so that the takoyaki can be cooked by heating. It is configured.

  However, in the prior art, since the motor which is a vibration generation source is provided on the bottom cover via the elastic body, the vibration is absorbed by the elastic body and the vibration cannot be sufficiently transmitted to the frame body. As a result, there is a problem that the heating plate cannot be vibrated sufficiently, and the ingredients poured into the heating plate cannot be uniformly heated and baked in a short time.

  In each of the above prior arts, the heating plate is configured to vibrate only in the direction in which the vibration components in the two perpendicular directions in the vertical direction and the horizontal direction are combined. Therefore, the heating plate is not in the longitudinal direction perpendicular to the horizontal direction. Even if it does not vibrate or vibrates in the front-rear direction, its amplitude is small, and thus there is a problem that it is difficult to heat cook the material for takoyaki into a substantially spherical shape. Furthermore, in each of the above prior arts, the configuration for converting the rotation of the motor into a vibration in which the vibration components in the vertical direction and the horizontal direction are combined and transmitted to the heating plate is complicated, and thus the number of parts is large. There is a problem that not only the weight of the apparatus increases, but also the manufacturing cost becomes expensive.

FIG. 5 is a developed plan view showing the configuration of the base 10.
The base 10 includes a base 30 and first to third support pieces (31, 32, 33) extending radially from the peripheral edge of the base 30 at equal intervals in the circumferential direction. A substantially semi-disc-shaped horizontal portion 35 in which the respective base ends of the second and third support pieces are connected to each other, and the horizontal portion is bent and connected at an angle θ1, and the base end portion of the first support piece 31 is connected.

The base 30 is formed with a motor mounting hole 34 that is open over the horizontal portion 35 and the inclined portion 36 and into which the motor 12 is inserted.

  The angle θ1 formed by the base portion 30 with the horizontal plane is selected from 15 ° to 30 °, preferably 24 °. If the angle θ1 is less than 15 °, the vibration component in the vertical direction is insufficient, and the adhesion of the material poured into the concave portions 41 cannot be reliably prevented. If the angle θ1 exceeds 30 °, the vertical direction is excessive. There is a possibility that takoyaki will be detached from the respective concave portions 41 of the food heating plate 2 due to the vibration component. Therefore, the angle θ1 is preferably 15 ° or more and 30 ° or less.

  The first support piece 31 includes a first bent portion 31a continuous via a first inner bent portion, a second bent portion 31b connected to the first bent portion 31a via a first outer bent portion, and a second bent portion. A third bent portion 31c is connected to 31b via a second inner bent portion, and a fourth bent portion 31d is connected to the third bent portion 31c via a second outer bent portion.

  The second support piece 32 has an axis m2 that forms an angle θ2 on one side in the circumferential direction on a virtual horizontal plane parallel to the paper surface of FIG. 5 with respect to a virtual vertical plane S1 including the axis m1 of the first support piece 31.

  The second support piece 32 includes a first bent portion 32a connected via a first inner bent portion indicated by a broken line, a second bent portion 32b connected to the first bent portion 32a via an outer bent portion, and a second bent portion. A third bent portion 32c is connected to the portion 32b via a second inner bent portion, and a fourth bent portion 32d is connected to the third bent portion 32c via a second outer bent portion.

  The third support piece 33 is formed symmetrically with the second support piece 32 with respect to the vertical virtual plane S1, and the subscripts “a”, “b”, and “c” are added to the corresponding portions 33. The description is omitted to avoid duplication. The base 10 is formed by punching a plate-like body made of, for example, a steel plate as shown in FIG. 5, bending the punched plate-like body, and the first to third support pieces 31-3. This is realized by forming each bent portion formed in 33.

  FIG. 6 is a plan view showing a state in which the base 10 is attached to the housing 4, and FIG. 7 is an enlarged cross-sectional view taken along section line VII-VII in FIG. FIG. 8 is an enlarged cross-sectional view taken along the section line XI-XI in FIG. The aforementioned base 10 is supported on the upper portion of the housing 4 via a plurality of (three in the present embodiment) springs 11. A substantially L-shaped bracket 14 for supporting the springs 11 on the inner wall surface of the housing 4 is equidistantly spaced in the circumferential direction by screws, and the first to third support pieces 31 of the base 10 are provided. To 33 for each position.

  A lower end portion of the spring 11 is fixed to each bracket 14 by a washer and a screw (not shown). Similarly, an upper end portion of each spring 11 is also fixed to the first to third support pieces 31 to 33 by a washer and a screw (not shown). It fixes to each 2nd bending part 31b-33b. In this way, the base 10 is supported on the upper portion of the housing 4 via the springs 11 in a state where displacement due to vibration is allowed. Further, since the base 10 is supported by the housing 4 via the plurality of springs 11, when the food heating plate 2 is heated by the heating means 21, the base 10 is heated by the radiant heat from the food heating plate 2. However, the amount of heat transmitted from the base 10 to the housing 4 is reduced by the heat radiation by the springs 11, and the housing 4 is prevented from becoming a high temperature due to the heat transfer from the food heating plate 2. Each of the springs 11 is realized by a compression coil spring made of stainless steel or spring steel, for example.

  Referring again to FIG. 1, the motor mounting hole 34 formed in the base 30 is mounted in a state where the motor 12 is inserted, and is fixed to the base 10 with a plurality of screws. The motor 12 is realized by an AC motor, for example. A weight 13 is attached to the output shaft 15 of the motor 12 at a position shifted from the center of gravity toward one end in the longitudinal direction. In this embodiment, the weight 13 is made of a flat, substantially rectangular metal plate having a mass m of 20 g. Thus, by making the weight 13 into a flat, substantially rectangular shape, the occupied space when the weight 13 rotates can be reduced, and vibration with a large amplitude can be generated.

The motor 12 is supplied with electric power from a commercial AC power supply by turning on the vibration switch SW2 provided in the housing 4, and the output shaft 15 of the motor 12 is set at a constant rotational speed, for example, 1000 to 1500 rpm. It is rotationally driven in the direction. The rotation of the output shaft 15 causes the weight 13 to rotate about the inclined axis, and the motor 12 vibrates. The vibration of the motor 12 is transmitted to the food heating plate 2 via the base 10.
Thus, since the weight 13 is rotationally driven at a high speed of 1000 to 1500 rpm, the food heating plate 2 is vibrated at a high cycle, and the takoyaki is rotated and heated uniformly while preventing the scorching of the takoyaki. In addition, the baked takoyaki can be kept warm without scorching.

  FIG. 9 is a bottom view of the housing 4. A substantially disc-shaped back cover 5 is attached to the bottom of the housing 4. A plurality of mounting pieces 50 are integrally formed at the peripheral edge of the back cover 5 at equal intervals in the circumferential direction. Further, a substantially L-shaped back cover bracket 16 for supporting the back cover 5 is provided at the lower end portion of the housing 4 at regular intervals in the circumferential direction by screws, and each mounting piece of the back cover 5 is attached. It is fixed to protrude radially inward at a position corresponding to 50. The back cover 5 is attached so as to close the lower portion of the housing 4 by fixing each attachment piece 50 to the back cover bracket 16 with screws in a state of being fitted into the lower portion of the housing 4. The back cover 5 is attached with vibration-proof rubber legs 7 having a substantially cylindrical shape in the vicinity of the mounting pieces 50 formed on the back cover 5 by screws, and is takoyaki on a mounting table such as a table. In the state where the apparatus 1 is placed, the vibration of the takoyaki machine 1 can be absorbed, and the vibration of the entire takoyaki machine 1 can be relaxed and supported stably.

FIG. 10 is a side view of the housing 4. Referring also to FIG. 2, a plurality of through holes 51 are formed in the housing 4 in a zigzag manner at intervals in the axial direction and at different positions in the circumferential direction. By forming the plurality of through holes 51 in the housing 4 in this way, the housing 4 has an opening ratio of about 50% to about 70%, imparts air permeability to the space in the housing 4, and the heating means 21. Thus, when the food heating plate 2 is heated, the housing 4 is prevented from being heated by the radiant heat, and the safety is improved so that the user does not touch the housing 4 and get burned. Further, since the plurality of through holes 51 impart air permeability to the housing 4, it is possible to prevent the motor 12 from being heated by radiant heat from the heated food heating plate 2. Even if it is used for a long time, the excessive temperature rise of the motor 12 is suppressed, and the motor 12 is prevented from being seized.
In the present embodiment, the housing 4 has a cylindrical shape, but is not limited thereto, and may be a polygonal cylindrical shape such as a dodecagonal cylindrical shape.

  Next, operation | movement of the takoyaki machine 1 mentioned above is demonstrated. First, when the plug of the power cord 6 is plugged into a commercial AC power outlet and the heating switch SW1 is turned on, power is supplied to the heating means 21 and the heating resistance wire 60 in the heating tube 45 generates heat, thereby heating the food. Plate 2 is heated. After placing an appropriate amount of oil in each recess 41 of the food heating plate 2 and confirming that the heating means 21 has reached an appropriate temperature, a fluid dough prepared in advance is poured into each recess 41. Add ingredients such as dregs, green candy, and red ginger. Here, the dough is a fluid material obtained by dissolving flour with water. Moreover, what added ingredients, such as the said fluid dough and octopus, and toppings, is called Takoyaki seed.

  Next, when the outer surface of the dough in each recess 41 is hardened, the vibration switch 3 is operated to drive the vibration means 3. As a result, the motor 12 is driven, and the weight 13 attached to the output shaft 15 of the motor 12 rotates to generate vibration.

  As described above, the motor 12 which is the vibration means 3 is provided in a state where the axis of the output shaft 15 is inclined with respect to the vertical axis, and the weight 13 is output from the motor 12 at a position away from the center of gravity. The shaft 15 is connected. Therefore, the vibration generated by the vibrating means 3 can generate a vibration in which three vibration components in the vertical direction, the horizontal direction, and the front-rear direction are combined.

  Such a vibration means 3 gives the food heating plate 2 a vibration in which three vibration components in the vertical direction, the left-right direction, and the front-back direction are combined, and only the vicinity of the surface is hardened in the recess 41 of the food heating plate 2. The substantially hemispherical takoyaki rotates mainly in the front-rear direction while maintaining an appropriate contact state from the inner surface of each recess 41 by vibration in the vertical direction and the left-right direction. As a result, the takoyaki is not biased in each recess 41 It burns into a roughly spherical shape.
